FURNACE GBATE.

Application filed February 5, 1921. Serial No. 442,785.

T 0 all whom it may concern.

Be it known that I, SAMUEL B. Morr, a citizen of the United States, and a resident of Noblesville, county of Hamilton and State of Indiana, have invented a certain new and useful Furnace Grate; and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention relates to a grate for furnaces and the like and more particularly to the means for ren'ioving the ashes and clinkers so as to retain a free passage for the draft. This is accomplished by means of a revolving grate provided with a similar surface on each side, whereby it can be turned about a half revolution so as to present the under side for the support of the fire, the revolving movement causing the ashes and clinkers to be completely dumped into the ash pit.

The feature of the invention is the manner in which the grate is mounted and actuated, and locked in fixed position.

Another feature of the invention is the construction and mounting of the removable grate plates whereby they may be replaced when broken or removed for cleaning.

The full nature of this invention will be understood from the accompanying draw ings and the following description and claims:

Fig. l is a plan view of the grate in position to receive the fire Fig. 2 is a front elev ation of a portion of a furnace showing the position of the grate in dotted lines. Fig. 3 is a section taken on. the line 3-$-3 of Fig. 1. Fig. l is a perspective view of one of the grate plates. Fig. 5 is a section taken on the line 5-5 of Fig. 1. Fig. 6 is a fragmentary longitudinal section of the grate taken between two of the bars and showing the relation between the grate bar, its supporting bars and the grate frame.

In the drawings there is shown a fire pit for a furnace having the walls 10 and front faces 10* in which is horizontally mounted a grate 11 for supporting the fire. The grate is formed of twin supporting frame members abutting each other on one side and secured together by the bolts 12. Mounted in the apertures of the frame members there are a plurality of grate plates 13 supported by means of cross bars 14 extending through the members and the end notches 15 of the grate plates. The cross bars 14 are removable from the frame member endwise and upon their removal the plates 13 can be taken out for replacement or cleai'iing. F or properly spacing the plates from each other, each plate is provided with a plurality of lugs or projections 16 at substantially the four corners thereof, which are adapted to bear against the adjacent plate, as shown in Figs. 1 and 3.

Each end of the grate frame members is provided with a. forwardly extending sup port 17 adapted to extend into the bearings 18 in the walls 10, in such a manner that the grate will be supported and balanced so as to revolve in said bearings. Extending into and secured to the forward support 17, there is an operating bar 19, upon which may be fitted the usual operating lever 20 for turning the grate ov'er through a half revolution so as to present the under side to the top. For maintaining the grate in its horizontal position, there is provided an arm 21 secured to the operating bar 19, through the end of.

whic-h'extends a pin 22 which may he in sorted in the hole provided for: the purpose in the end of the wall 10 at the proper location I hen it is desired to clean the fire pit, instead of shoveling or shaking out the ashes and clinlrers, the pin 22 is removed, the lever 20 placed in position and the entire grate turned through a half circle, the pin 22 is then inserted on the opposite side, shown in dotted lines in 2, the operating lever removed and the furnace ready to be tired again, If for any reason the grate plates must be removed or the space between them becomes choked, the grate need only be turned at an angle so the cross bar 1 1 can be removed and each of said. plates may then be readily taken out.

The invention claimed is:

1. In, a furnace, a fire grate comprising a supporting frame having a plurality of frame members, each of said members having a plurality of apertures therein, a projection extending from each end of each of said members arranged to provide end supporting ournals therefor when placed adjacent each other, for rotatably supporting said grate in said furnace, a plurality of removable plates supported by said members Within said apertures, and means for engaglng sald PI'OJGCUODS tor; turnlng said grate 1n the furnace.

2. In a furnace, a fire grate comprising a 10 and supported by said framefor providing grate surfaces and each having a notch in each end thereof, and rods remova'bly mounted in said frame seated insaid notches for removahly securing said plates therein, said plates having means for spacing them from each other.

In Witness whereof, I have hereunto affixed my signature.
